Target and Non-Target Lepidopteran Pest IPM in Brazil Bt Crop Refuge Areas
Journal Title: World Journal of Agriculture and Soil Science - Year 2019, Vol 2, Issue 1
Abstract
Among the largest fibers and grains cash crop, Brazil is one of the largest commodity agricultural producer in the world. However, the insect’s pest intense attack has limited the Brazilian agricultural crops productivity and sustainability of the main as soybean, corn and cotton [1]. After genetically modified crops expressing insecticidal proteins from Bacillus thuringiensis bacterium (Bt) market released as Integrated Pest Management (IPM) tool, especially for Lepidoptera order pest control, most of growers believed that losses by insect pests damage would be minimized. In fact, Bt has been effective to a target pest group, however the Insect Resistance Management to Bt plants (IRM) has not been implemented and resistance cases came out and technologies failures have been recorded [2,3]. The main IRM strategy have been adopted are Bt plants expressing high dose protein insecticide associated with refuge areas (non- Bt plants). However, in most crops field pest resistance cases to Bt were connection to low refuge areas adoption [4]. Thus, to ensure field efficacy Bt crops requires growing the refuge area and pest management insights [5].
